/**
 * Abstract base class for all resolvers using SSH All necessary connection parameters can be set
 * here via attributes. However all attributes defined in the pattern url of the resolver will have
 * higher priority and will overwrite the values given here. To specify connection parameters in the
 * pattern, you have to specify a full url and not just a path as pattern. e.g.
 * pattern="/path/to/my/repos/[artifact].[ext]" will use all connection parameters from this class
 * e.g. pattern="ssh://myserver.com/path/to/my/repos/[artifact].[ext]" will use all parameters from
 * this class with the exception of the host, which will be "myserver.com" e.g.
 * pattern="sftp://user:[email protected]:8022/path/to/my/repos/[artifact].[ext]" will use only
 * the keyFile and keyFilePassword from this class (if needed). Rest will come from the url.
